Putting All Pages in a Single Task Flow
You can also design an application in which all application activities reside within the ADF-unbounded flow. This mimics a Struts or JSF application, but does not take advantage of ADF bounded task flow functionality. To take full advantage of the task flow functionality, use ADF bounded task flows.
You typically use an unbounded task flow if:
You want to take advantage of ADF Controller features not offered by bounded task flows, such as bookmarking view activities.
You do not need ADF Controller features that are offered when you use a bounded task flow.
The task flow will not be called by another task flow.
The application has multiple points of entry.
